  • Insulator strings can be frequently damaged by fault currents occured by lightning strokes, overvoltages and contamination of the insulators. So the Insulator damages may lead to extensive damages to transmission lines as well as power outages that have caused dangerous situations to occur. This paper suggests the characteristics of arcing horn in relation to the protection of insulators and basic design concepts of the arcing horn for transmission lines.

  • This study evaluated electrical characteristics of the manufactured arcing horn whose rated voltage and nominal discharge current were 18kV and 2.5kA, respectively. In this study, residual voltage and lightning impulse flashover voltage were examined. The arcing horn showed excellent electrical characteristics that residual voltage and lightning impulse flashover voltage were 55kV below and 121kV at 115mm, respectively. Therefore the manufactured arcing Horn is considered that it would show good performance for protecting electrical wires and line post insulators from lightning impulse, if it were applied to real fields.

  • 154kV insulator strings are frequently damaged by lightning strokes, overvoltage and contamination. And this insulator damage inflicts a loss on the power company. The purpose of this paper is to develop the arcing horn as a protective device of 154kV insulator strings against lightning flashover and overvoltages. So We have developed the arcing horn which is suitable for 154kV transmission line and estimated the performance of arcing horn by high current arcs and high voltage tests.

  • 765kv Transmission lines of the contaminated areas need many insulators due to the contamination. So the length of the arcing hem is very long. Because it is very difficult to install the arcing hem on insulator string sets due to its length, we must install the arcing horn on the jumping devices, and studied about the jumper horn. This paper described the investigation and analysis of the installation status of the arcing horn, and the design of the jumper horn for 765 kV transmission lines.

  • Insulators of 154kV T/L have been frequently damaged by fault currents. Arcing horn is a very effective and economic method for protection of insulators from the flashover. We developed arcing horns for 154kV T/L in order to protect insulators from the arc[1]. This paper analyzes the status of insulator failures in 154kV T/L after installation of the arcing horns.

  • The same sized arcing horns have been installed on 345 kV transmission lines. Then arcing horn gaps are different according to the insulator string set. We need to examine the problems about the gap differences. So, we investigated the installation status of acing horn in 345 kV T/L. Based on these results. Drawing and making of the arcing horns for the contaminated areas is studied.

  • Insulators of transmission line have been frequently damaged by lightning flashover. Arcing horns have been installed on string sets to protect insulators from the flashover. But reclosing number can be increased by the decrease of insulation strength and they are worrying it. Then this paper analyzes the installation effects of the arcing horn.

  • The simulation study of lightning faults reducing effects by the installation of surge arresters on the 154 kV transmission line is stated here. For the purpose of detailed simulation of arcing horn, a flashover model with dynamic characteristics of arcing horn gap was represented as a non-linear inductance which is controlled by EMTP/TACS(Electromagnetic Transient Program/fransient Analysis of Control Systems) switches. The back flashover inducing current was increased from 50 kA to 88 kA by the installation of surge arresters on the transmission line which has one ground wire and 20 ohms of tower footing resistances. The great advantage of surge arrester installation on one circuit of the double circuit transmission line is to prevent the simultaneous back flashover up to 190 kA.

  • This paper presents a characteristics of horizontal swing angle in V type suspension string sets for 765kV T/L. The design of V type suspension string set does not differ from that of general string set for general towers, but it prevents instabilities from swing motion by the horizontal angle and by the wind pressure. We were designed specially 6 conductor yoke, arcing horn and earth horn. And we were decided to 550mm for a distance of strings. We were carried out characteristics of horizontal swing test and movement of mass center test for V-string sets of 400kN single, 300kN double and 400kN double. This products will be used for 765kV T/L of 1 circuit in suspension towers.
